Ubuntu 10.10 Screenshot of full screen works. Screenshot of "selected area" works. But Screenshot of current (active) window doesn't. Nothing happens. The save screenshot window doesn't open.

Tried using Alt+Print as well as from the Panel->Accessories->Screenshot. Same result. No screenshot.

GIMP window screenshot works. But thats not the point. Why doesn't the normal way work?

Any ideas?


In Ubuntu 10.10, Alt+PrtScrn conflicts with Magic SysRq. Run the following command to fix it:

sudo sysctl -w kernel.sysrq=0

More info can be found here: UbuntuGuide

EDIT: An alternative is to set it to a different key combination in the Keyboard Shortcuts settings window. The option to look at is "Take a screenshot of a window"

EDIT 2: A helpful troubleshooting link was suggested in the comments below: (AskUbuntu question)

  • Thanks for the prompt answer. That does it. Didn't want to meddle with the Magic SysRq key so changed the keyboard shortcut. And now it works! – Cocoro Cara Mar 17 '11 at 14:06

    @Cocoro Feel free to accept the answer so that we both get credit for the question :-) – Hyppy Mar 17 '11 at 14:12
  • To use the Panel -> Accessories -> Screenshot method, one needs to increase the delay above 0 seconds and click on the window. See here – Cocoro Cara Mar 17 '11 at 14:23
